The main feature of TimeLeft is a powerful customizable reminder, which can alarm you at a specific moment of time or run periodically (minutely, hourly, daily, weekly, monthly or annually). It can also remind you before a specified event or keep on reminding after it. Reminder can show a message, play music or open a link/document, execute an application or shutdown your PC. Numerous other options are also available: multireminder, time bounds etc.

One more beautiful TimeLeft feature is a customizable countdown, which lives on your desktop and shows the amount of time left to (or passed after) the specified event. Countdown may be easily used in a businesslike way, to remind you of forthcoming events (meetings etc.) or job to be done. But even if you are not a business type of person, you can still use TimeLeft to just add some extra excitement to your life watching how the time left to some eagerly awaited event (be it a cruise or your friend's visit) is getting less and less.

Other TimeLeft features include:
clock, stopwatch, timer, desktop sticker, time synchronization, placing countdown on a web-page and more.
